1) AC Mains
This is the AC cord for connecting to 120VAC mains, 60Hz, 40W. Certain export models
connect to 230V and are labelled accordingly.
2) Main Speaker Outputs
This 5.08mm Euroblock connector is used for speaker output wiring. For low impedance
speaker loads, connect between the COM and 12V/4
Ω
terminal or COM and 17V/8
Ω
terminal. For
25V or 70V distributed speaker applications, connect the speakers between COM and 25V or 70V
terminals, depending on the transformers/speakers used. For distributed speaker loads on 230V
export models, connect between COM and 70V or 100V terminals.
3) CD/Satellite Input
These RCA inputs accept a stereo line level signal and sum them to mono on channel 3 input.
To use the CD/Satellite RCA inputs, be sure to set the channel 3 Select switch (#4 below) to the left.
4) Input Select Switch
This switch selects either the stereo line level input on RCA jacks, or mic level input on the
MIC 3 Euroblock connector.
5) MIC 3 Input
This 3.5mm Euroblock connector is used for MIC 3 input. To use the MIC 3 input, set the
channel 3 SELECT switch (#4 above) to the right. Wire the microphone (+) signal to pin 1, the (-)
signal to pin 2, and (G) to pin 3. If wiring an unbalanced mic input signal into a balanced Euroblock
input, be sure to ground the (-) input pin.
6) MIC 1 Input
This 3.5mm Euroblock connector is used for MIC 1 input. Wire the microphone (+) signal
to pin 1, the (-) signal to pin 2, and (G) to pin 3. If wiring an unbalanced mic input signal into a
balanced Euroblock input, be sure to ground the (-) input pin. MIC 1 input has ducking priority over
MIC 2 and MIC 3 inputs, with an adjustable ducking depth control. There is no phantom power
available on the TM-335.
